3 Uairns. till. 61-2) This invention relates to dredging and othermethods for removing sand bars, deltas, and other accumulations ofmaterials on river bottoms, inlets, and the like, and in particular anelongated structure having spaced converging baffles providing opencells extended across a river bed with a iluid injecting p-ump at oneside or" the river for forcing duid through jets in openings at one ofthe ends of cells and with a suction pump on the opposite side of theriver for drawing sand and other materials from the batiies or cells.

The purpose of this invention is to provide a sand remover that mayreadily be positioned in a sand accumulation at the bottom of a riverand that is designed to be operated with jet action to remove the sandfrom the river bed and deposit the said on a bank at one side of theriver.

Various types of dredging equipment have been provided for removingaccumulations of material on river beds are the like and some of suchequipment operates by suction or with jet action. However, for eicientoperation of such equipment it has been found desirable to provide sandarresting pockets or cells with fluid discharged through nozzles underpressure for withdrawing sand from said cells and with suction means forreceiving the sand and also conveying the sand to a remote point. Withthis thought in mind this invention contemplates an elongated opencasing having a plurality of cells therein with iluid dischargingnozzles positioned to create suction in the cells and with one pump forsupplying fluid under pressure to the nozzles, and another pump forcreating suction around the nozzles to facilitate Withdrawing sand fromthe cells.

The object of this invention is, therefore, to provide an elongatedtrough with transversely disposed partitions providing cells therein,with a pump at one end for discharging uid under pressure and with a jetaction through ends of the cells and with a pump at the opposite end fordrawing iiuid from the ends of the cells in which the jet action nozzlesare positioned.

Another object of the invention is to provide a sand remover for riverand bay bottoms in which the remover is designed to be assembled at theside of a river or bay and readily dropped into position with pumpsconnected to opposite ends thereof.

Another important object of the invention is to provide a river bottomaccumulation remover which is designed to be used for other purposes.

A further object of the invention is to provide a river bottom sandaccumulation remover having a pressure pump at one end and a suctionpump at the opposite end in which the remover is of a simple andeconomical construction.

With these and other objects and advantages in view the inventionembodies an elongated trough having spaced transversely disposedpartitions therein dividing the trough into cells with a pressure headerextended below the trough and having branch connections with dischargenozzles at ends thereof extended upwardly and into the cells and with apressure pump connected to the header and a suction pump connected tothe opposite end of the trough.

Other features and advantages of the invention will appear from thefollowing description taken in connection with the drawings, wherein:

FIGURE 5 is a sectional plan taken on line 5--5 of FIGURE 4 showing theconverging walls or bafes of the cells and also showing the jet actionnozzles in the small ends of the cells.

FIGURE 6 is a view looking upwardly toward they under side of the troughshowing the uid pressure header with the branch connections of thenozzles positioned in the cells.

FIGURE 7 is a cross-section through the trough taken on line 7-7 ofFIGURE 2.

Referring now to the drawings wherein like reference characters denotecorresponding parts the improved river bottom accumulation remover ofthis invention includes an elongated trough having a base 10, aplurality of converging baffles having inclined side walls 11 and 12 andsloping cover panels 13 mounted on the base and positioned with throats14 thereof aligned with a discharge nipple 15, pairs of nozzles 16 and17 positioned in the baflles, a supply header 18 having a nipple 19connected by a hose 20 through a pressure pump 21, the intake of whichis connected by a hose 22 to a perforated head 23, and a suction pump 24connected by a hose 25 to the discharge nipple 15 of the trough.

The length of the trough is such that the trough extends from one sideof a river bed to the other and the number and size of the baffles isdepended upon the size of the river.

As illustrated in FIGURES 6 and 7 the header 18 is provided with branchconnections 26 and Z7 that extend upwardly through the base 1) and, asillustrated in FIGURES 4 and 5 upper sections 28 of the branchconnections extend toward the discharge end of the trough and the endsof the sections 28 are formed to provide the nozzles 16 and 17.

The trough is provided with side walls 29 and 30 from which the inclinedside walls 11 and 12 of the baffles extend and the intake end of thetrough may be provided with an end plate 31, as shown in FIGURE 4.

Also as shown in FIGURE 4, the trough may be formed in sections, withsections 32 of the base extended upwardly overlapping adjoining ends ofthe base portions of the sections.

With the units assembled to form a trough, as illustrated in FIGURE 1,the intake nipple 19 of the uid pressure supply header 18 is connectedby the hose 20 to the pump 21 and the discharge nipple 15 is connectedby hose 25 to the suction side of the pump 24 whereby the discharge offluid under pressure through the nozzles 16 and 17 is accentuated by thefact that the nozzles are discharging into vacuum or suction whereby aiet action is produced so that sand sliding down the cover panels 13drops into a suction area and is discharged through the hose 25 and pump24. By this means, sand, as indicated by the numeral 33, in FIGURE l isremoved by jet action from a river bed and deposited on the bank at theside of a river bed. The discharge of the pump 24 may be provided with atube 34 by which the sand may be carried to a suitable point.

Although the trough is provided with pairs of jets or nozzles it will beunderstood that any suitable number of nozzles may be used and thebai-lle units may also be arranged in different designs.

It will be understood that modifications, within the scope of theappended claims, may be made in the design and arrangement of the partswithout departing from the spirit of the invention.
